+# mozdownload
+
+[mozdownload](https://github.com/mozilla/mozdownload)
+is a [python package](http://pypi.python.org/pypi/mozdownload)
+which handles downloading of Mozilla applications.
+
+## Installation
+
+If the tool should only be used for downloading applications we propose to
+install it via pip. The following command will install the latest release:
+
+    pip install mozdownload
+
+Otherwise follow the steps below to setup a development environment. It is
+recommended that [virtualenv](http://virtualenv.readthedocs.org/en/latest/installation.html)
+and [virtualenvwrapper](http://virtualenvwrapper.readthedocs.org/en/latest/)
+be used in conjunction with mozdownload. Start by installing these. Then first fork
+our repository into your own github account, and run:
+
+    git clone https://github.com/%your_account%/mozdownload.git
+    cd mozdownload
+    python setup.py develop
+
+More detailed developer documentation can be found in the [wiki](https://github.com/mozilla/mozdownload/wiki).
+
+## Command Line Usage
+
+The `mozdownload` command will download the application based on the provided
+command line options.

+## API
+
+Beside the CLI mozdownload also offers an API to be used. To create specific instances of scrapers
+the FactoryScraper class can be used. Here some examples:
+
+    # Create a release scraper for the German locale of Firefox 40.0.3
+    from mozdownload import FactoryScraper
+    scraper = mozdownload.FactoryScraper('release', version='40.0.3', locale='de')
+
+    # Create a candidate scraper for Windows 32bit of Firefox 41.0b9
+    from mozdownload import FactoryScraper
+    scraper = mozdownload.FactoryScraper('candidate', version='41.0b9', platform='win32')
+
+    # Create a daily scraper for the latest Dev Edition build on the current platform
+    from mozdownload import FactoryScraper
+    scraper = mozdownload.FactoryScraper('daily', branch='mozilla-aurora')
+
+All those scraper instances allow you to retrieve the url which is used to download the files, and the filename for the local destination:
+
+    from mozdownload import FactoryScraper
+    scraper = mozdownload.FactoryScraper('daily')
+    print scraper.url
+    print scraper.filename
+
+To actually download the remote file the download() method has to be called:
+
+    from mozdownload import FactoryScraper
+    scraper = mozdownload.FactoryScraper('daily')
+    filename = scraper.download()
